The Lowdown
Alright folks, let's be real with each other. I’ve been staring at this forecast for Kennebunk Beach for the next couple of weeks, and I’ll tell you right now, the surfboard is staying in the car for a while. This is a tough stretch. We’re looking at a solid run of tiny, weak, and messy waves that just won’t give us anything to work with.
The first week is a total write-off. From Sunday the 9th right through the following Saturday, we’re dealing with ankle-biters. Swell heights are hovering around that 0.3ft to 2ft mark, and the energy is pathetic. The combined wave energy is struggling to get out of single digits most days, which tells you everything you need to know. The winds are mostly cross or cross-onshore, chopping up an already flat ocean. There’s a brief moment on Wednesday the 12th morning with a clean, slight air and a cross-offshore breeze, but the swell is still just 0.3ft. You could paddle out and get a nice tan, but you won’t be catching anything. It's a long, flat, and frustrating gap with no surf on offer.
Things start to rumble a little toward the end of the second week, but it's still not looking good for us. The swell energy picks up, but the quality is just… poor. We see the combined energy start to hit three-digit numbers from Thursday the 20th and into the weekend, but the direction is all wrong and it’s still messy. By Saturday the 22nd, we finally see some real size – 5ft in the morning building to 6ft by the afternoon. But it’s coming from the Southeast with a short, weak period of 5-6 seconds, and the wind is cross-shore. That’s not a clean, playful wave; that’s just a bumpy, fat mess. The water temp is about average for this time of year, so at least you won’t need a thick suit, but that’s about the only positive.
Sunday the 23rd has a bit more size, with 6ft in the afternoon, but the energy is still disorganized and the wind is cross-onshore. It's a similar story on Monday the 24th, with 4ft but a moderate cross-onshore breeze. This is the kind of surf that’s just too big and messy for the beginners, but with that short period and poor wind, it’s not even good for the experts. Honestly, if you’re looking for a silver lining, this setup looks far more interesting for the kite surfers than it does for us paddle surfers. There are no standout days, no hidden gems, just a long stretch of disappointment. The long-range stuff is promising in size but the quality is just not there. I’d say keep your board in the bag and maybe check back in a week or two; forecasts can change, but this one needs a lot of help.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
